I wonder why I didn't see that warning. Not with allmodconfig, and not with my normal build. [ Looks around ] Hmm. Apparently "allmodconfig" doesn't actually enable memory hotplug. And the reason is that allmodconfig enables KASAN, which then disables MEMORY_HOTPLUG. I wonder if we should make KASAN depend on !COMPILE_TEST, because it does seem to disable a lot of build-time testing. Oh well. I'll remove the stupid unused variable, thanks for the heads-up.
